A prescription calls for VI fl oz of promethazine syrup. What size bottle should the pharmacy technician use?

To determine the correct size bottle for a prescription that calls for VI fl oz of promethazine syrup, it is important to convert fluid ounces to milliliters. The conversion factor used is that 1 fl oz is approximately equal to 29.57 mL.

When converting VI fl oz (6 fl oz), the calculation is as follows:

6 fl oz x 29.57 mL/fl oz = 177.42 mL

When rounding, this generally would be rounded to approximately 180 mL.

To select the appropriate bottle size, you want a container that can accommodate the required volume without being too small. Since the requirement is close to 180 mL, choosing the 180 mL bottle will ensure adequate space for the medication while minimizing leftover volume.

In summary, selecting the 180 mL bottle aligns perfectly with the calculated volume needed for the prescription of VI fl oz of promethazine syrup. This ensures that the patient receives the correct dosage without issues related to oversizing or waste.
